Furthermore, Gore intends to play next year in what will be his 15th season in the NFL, Rapoport added.
The 35-year-old will need to find a new deal and potentially a new team this offseason.
Gore averaged at least 4.6 yards per carry for the first time since 2012 and averaged a career-high 10.3 yards per reception. His 168 touches and 846 total yards were his fewest since his rookie year, but Gore proved a capable lead back and occasional No. 2 option for the contending 'Fins. The back finished with a team-high 722 rushing yards.
The Inconvenient Truth ends the season ranked fourth all-time in rushing yards with 14,748, behind only Emmitt Smith, Walter Payton and Barry Sanders. Turning 36 in May, Gore will enter 2019 just 522 rushing yards shy of passing Sanders for third all-time.
